The invention discloses a composite material reinforced bulkhead, a manufacturing mold of the composite material reinforced bulkhead and a forming method of the composite material reinforced bulkhead, and relates to the technical field of bulkhead structure equipment. The reinforcing bulkhead comprises a frame body, a foam core and reinforcing ribs, the frame body is formed by laying a composite material, and a reinforcing layer is arranged in the composite material laying layer. The manufacturing mold of the composite material reinforced bulkhead comprises a base plate, an outer mold and a base, and the base plate is provided with a protruding part consistent with a through hole in shape at the position of the through hole of the reinforced bulkhead. The forming method of the composite material reinforced bulkhead comprises the steps of overall laying of the composite material, laying of the reinforced layer and final laying of the part exceeding a pre-laying layer, and removing an isolating membrane, so that overall laying of the reinforced bulkhead is completed. The bulkhead has the advantages that the local strength and rigidity of the bulkhead are enhanced, the integrity is high, and the problems that the connecting strength with aircraft parts is insufficient, and the bulkhead is heavy are solved.
